To all'whom it may concern Be it known th t I, WILLIAM D. FORSYTH, a citizen of the United States, residing at Youngstown, in the county of Mahoning' and State of Ohio, useful Improvements in Forgings for'C'ar- Truck Side) Frames, of which the following is a specification. I

' This invention relates to forgings for car truck side frames made from a single piece of railed metal.

One of the objects ofthis invention is to provide a forging of such cross section that themetal' may be distributed in the top and {bottom memb,ers of the forging, and the bolster opening therein may be so placed as said top and bottom members-more e etive as to strength and clearance between the car body and the top of the rails of the track, the position of the bolster opening cooperating with the distribution of the metal in the top and bottom members of the forging to permit the clearance between th car body and the top of the rails, as afore? said, to be more effectively adjusted. The invention consists, among othkr things, of. a forging for a .car truck. de

frame made from. a single piece of mital,

flanges connected by a web, with unequal amounts of 'metal in said flanges and a bolster opening made-in said web by slotting the same along its longitudinal axis, between removing from said web a part thereof betweenthe upper edge of said slot and the lower side ofthe top flange of the section and expanding said web substantially at right angles to said slot; with the ends'of both top and bottom flanges arranged so that they shall be over the top of theaxle of the car to which the car truck side frame into the construction of which said forging enters, is attached, as herein more specifically described.

In the accompanying drawings, Figure 1 is 9. rolled metal section; Fig. 2 is view of Fig. 1; Fig.3 is a side view of Fig. 1, with the flanges and web cut and punched preparatory to expansion; Fig. 4 is a forging after the same has been expanded and the lower flange conformed to the free outer top flange. Y

Like figures ofreference refer to l ke parts throughout.

have invented new and' bottom flange 2. rolled section. having two ends 11, connected 'parts 12, 12', will constitute the tension meman end and the undersides of the stem rename ron oAnrrRUcK'sInn animus-" Patented Jan. 6, 1914.

In Fig. 1, 1 is a rolled seotionyhaving a top flange 2; a-web 3; abottom flange 4, which is'rolled so as to have the cross section shown in Fig. 2; the top flange 2 having a longitudinal groove 2. throughout its length, and while bottom flange 4 has not said longitudinal groove, it may have such. longitudinal groove indicated by dotted lines 4. in Fig. 2. Preparatory to expanding said rolled section, web 3 is cut away between the ends of the flanges; top' flange 2 is. made.

' shorter than bottom-flange 4; slot 5 is made in the central part of said web, and that part 5 of the web, between the underside of top flange 2, thetop of slot 5 and vertical lines- 6, 6, is punched out so that the rolled section 1 shall take the form shown in Fig. 3. The rolled section 1 as thus formed, either while hot or. cold, by suitable apparatus is ,pressed so that the web thereof shall be ex-- lpanded substantially at right angles to slot 5, and so that the top and bottom flanges shall takethe form shown in Fig. 1. When this formation has taken-place, top flange 2 has a central part-'7 at ends 8,'8, connected by downwardly, extending parts 9, 9, and 4 has a central part 10 at ends 11, 11, connected to central part .10 by downwardly extending parts 12, 12. -The ends'll of 4: are so bent'as-to contact with the edges 13, 13, of the web and the under sides of the ends 8, 8, of the top flange 2, between points 14 and 15;'the expansion of the web-,- as aforesaid, causes the'fo'rmation of the bolster opening 16 in the forging.

The flange. 2,c.onsisting of central part 7 and ends 8', 8, connected by downwardly inclined parts 9, 9., will constitutethe compression member of any car truck 'side' frame into the construction of which the forgingherein described enters, and bottom' flange 1-, consisting of central part 2 and by upwardly extending ber in such car truck side frame.

In Fig. 4 thedotted lines 17, 17 and 18, 18, indicate the bottom of 'the groove 2' in the topflange and the bottom of the groove 4. int-he bottom flange, if saidbottom flange be made with said groove. Any of the metal of said'flanges above dottedlines 17 '17, or below dotted lines 18, 18, maybe removed. For instance, if the metal be removed between points 19, '19 on the top flange, if the said flange bean inch and a half deep, it will a'fiord clearance to that extent between the-car body of the car and the top of the car truck side frame in which "said forging may be used," and if in like manner the'nietal in'the bottomflange, be-

tween points-20, '20, be removed, it will afford clearance to the depth of groove 4 therein," between the bottom of the forging and the top of the rail.' The removal of a partjof thewcb at 5 enables an adjustment ofthe bolster-ofjthe car truck in which the forging is used in a vertical line andat vthe ,sections for the top and bottom flanges of the'l rolled section, any cross section maybe i used wliicli'will permit a difl'erent' distribu- 1 XVhat I claim as my inventionis:
